Thermal magnetic circuit-breaker with 10kA breaking capacity, 4-pole configuration, 13A rated current, B-curve tripping, IP20 finger-safe design, and advanced current limiting for reliable protection against overloads and short-circuits in residential and small commercial applications.
The Legrand TX3 MCB TX3 10000A is a thermal magnetic circuit-breaker designed to provide reliable protection for wiring installations against overloads and short-circuits. With a breaking capacity of 10kA at 400V, this device offers precise protection with B-curve tripping characteristics that ensure activation between 39A and 65A. The 4-pole configuration with 13A rated current makes it ideal for residential and small commercial applications where comprehensive circuit protection is essential. The device features IP20 finger-safe design, protecting against solid bodies larger than 12.5mm, ensuring safe operation in various environments.
This circuit-breaker incorporates advanced current limiting technology (Class 3) that minimizes let-through energy during fault conditions, providing maximum protection for connected equipment. The TX3 is equipped with a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar supplying the row remains in place. The product includes a convenient label holder for clear circuit identification and On/Off indication printed on the handle with red and green backgrounds for easy status identification.
The MCB TX3 is fully compatible with Legrand DX3 auxiliaries and accessories, offering flexibility in system design and expansion. It can be supplied by copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), providing multiple installation options. The device complies with all substance-restriction requirements and has been designed following environmentally conscious processes, making it a sustainable choice for modern electrical installations.
